剑道UI自动完成数据源读取运输只有一次 [英] Kendo UI AutoComplete datasource transport reads only once

问题描述

我变得疯狂的剑道UI自动完成组件。我用我自己的函数使用jQuery来访问数据，所以我必须设置自动完成dataSource.transport.read为函数。在code是这样的。

I'm becoming crazy with Kendo UI AutoComplete component. I'm using my own functions to access data with jQuery, so I have to set the AutoComplete dataSource.transport.read as a function. The code is something like this.

minLengthAtocomplete = 3;

$('#autocomplete').kendoAutoComplete({
    minLength : 3,
    filter : "contains",
    dataValueField : "key",
    dataTextField : "value",
    dataSource : new kendo.data.DataSource({
        transport : {
            read : _OnTransportRead
        },
        schema : {
            /* object schema */
        }
    })
});

function _OnTransportRead(e) {
    var text = $.trim(e.data.filter.filters[0].value);

    if (text && text.length >= minLengthAtocomplete) {
        _GetUsers(
            text,
            function onSuccess(data) {
                var users = [];
                 /* sets users with info in data */
                e.success(users);
            },
            function onError(error) {
                /* stuff with error */
            }
        );
    }
}

function _GetUsers(userName, onSuccess, onError) {
    /* Ajax to get users from DB */
}

这code完美运行，但 dataSource.transport.read 只调用了一次。我的文字的michae的第一搜索和自动完成组件运行其dataSource.transport.read预期。然后，我添加了一个以上的字母来搜索的'迈克尔'的，并且dataSource.transport.read永远不会再次调用。就是这么折腾！

This code runs perfectly, but dataSource.transport.read is called only the once. I do a first search with the text 'michae' and AutoComplete component runs its dataSource.transport.read as expected. Then, I add a one more letter to search for 'michael', and dataSource.transport.read is never called again. Is so frustrating!

我试图使用自动同步数据源属性，手动同步数据源，在数据绑定自动完成设置新的数据源对象，但没有运气。

I tried using autoSync dataSource property, manual dataSource Sync, set new dataSource objects on AutoComplete dataBound, but no luck.

我是什么做错了吗？什么我忘了？

What am I doing wrong? What am I forgetting?

先谢谢了。

推荐答案

您应该启用<一个href=\"http://docs.kendoui.com/api/framework/datasource#serverfiltering%20booleandefault\">serverFiltering为了使数据源每次提出要求。

You should enable serverFiltering in order for the data source to make requests every time.

$('#autocomplete').kendoAutoComplete({
    minLength : 3,
    filter : "contains",
    dataValueField : "key",
    dataTextField : "value",
    dataSource : new kendo.data.DataSource({,
        serverFiltering: true, 
        transport : {
            read : _OnTransportRead
        },
        schema : {
            /* object schema */
        }
    })
});
